The escape pipeline installed in the tunnel, and the safety of tunnel construction personnel

&Nbsp; As for the safety of the tunnel construction personnel, it is difficult to guarantee the safety of the tunnel construction personnel in the previous years
In case of tunnel collapse, it is difficult for the workers to survive, because the general tunnel collapse is a large area of gravel, the soil layer falls, and all of it is dust
If they cannot evacuate immediately, they will soon suffocate
The technical conditions in the previous years are poor, and there is no way
After a while, someone proposed to build a life passage with steel pipes, This can reduce personal injury and has certain effects
However, it is difficult to avoid one shortcoming, that is, the impact resistance of the steel pipe is not high, it is easy to deform, and the gravel falls down
Sometimes the steel pipe is directly sunken in half and cannot be recovered, so the workers can not climb out smoothly
At the critical moment, the safety factor is not high
Later, ultra-high molecular weight polyethylene pipes appeared, which have high impact resistance and can be restored to the original state after being stressed, just making up for the defects of steel pipes

1、 Escape piping requirements and Applications
Requirements and application of pipes for tunnel escape pipes
1
ensure that the thickness of tunnel escape pipe is not less than 30mm
2
the length of each tunnel escape pipe is 3M
3
the tunnel escape pipe can be removed manually, and the connection is firm and safe

4
when the tunnel escape pipe is temporarily removed, it shall be removed section by section
It is strictly forbidden to remove it in place at one time

5
the tunnel escape pipeline shall be flat, dry and smooth, and shall not be used for other purposes than emergency escape

2、 Zhongxiong pipe industry escape pipe, advantages of new tunnel escape pipe
The new anti impact tunnel escape pipe provides a very safe and reliable guarantee for emergency escape and rescue in highway and railway tunnel construction
&Nbsp;
&Nbsp (1) Extremely high wear resistance, with ultra-high molecular weight of more than 2
5 million, small wear index, and wear resistance 6
6 times higher than that of general alloy steel
The service life of the pipeline is greatly improved
&Nbsp (2) Extremely high impact resistance
This product meets the GB1843 standard
The impact toughness value of this product is very high in the existing engineering plastics

&Nbsp (3) Corrosion resistance, this product can resist the erosion of strong chemicals

&Nbsp (4) Good self lubrication self lubrication is very good
Low friction coefficient
No adhesion and scaling on the surface

&Nbsp (5) Unique low temperature resistance
This product has excellent low temperature resistance and can work at -269 ℃ to 80 ℃ for a long time
&Nbsp (6) It is easy to install, the specific gravity is only one eighth of the steel pipe weight, and it is convenient to disassemble and handle

3、 Characteristics of UHMWPE tunnel escape pipe
1
Ultra high molecular weight polyethylene (UHMWPE) tunnel escape pipeline has low material cost and saves procurement cost for engineering projects
　  　
2
The UHMWPE tunnel escape pipeline has strong corrosion resistance, the construction party is simple and quick, and the service life can reach 20-50 years 　
3
UHMWPE tunnel escape pipe also has good impact resistance under low temperature conditions 　
4
Ultra high molecular weight polyethylene (UHMWPE) tunnel escape passage is reasonably designed and easy to install
The tunnel escape pipe port is equipped with connecting parts and lifting rings
Installation, hoisting and convenience of tunnel escape pipeline
